    keyword=ep beam problems

    ep energy measurement problems:
    Before Thanksgiving break did ep measurement and had 0.4 Hz count rate at 5 micro Amps. If beam conditions were identical I would exepect 0.5 Hz at 6 micro Amps today. Instead I see 0.9 to 1 Hz countrates. Further there is no coplanarity peak.
    Under these conditions ep is not do-able.
